You will be able to go ashore in most ports if your work schedule permits. But keep in mind that the ship has the right to delay or cancel crew shore leave at any time. This can happen for various reasons. You may be required to attend a boat drill, the ship may dock late or maybe there are limited tender boats available to take you to shore if the ship has anchored.
Large ships often have a designated crew gangway. If you must use the passenger gangway, remember that passengers always disembark first. Also, don’t forget to bring your crew identification card with you when disembarking the ship. The crew onboard time is usually one hour prior to departing the port. It is very important to remember this because if you miss the ship, you are responsible for your own travel expenses to meet the ship at the next port. As well, be prepared to be summoned to Captain’s court.
